Do You Need a Permit to Build a Fence in Phoenix?
Only if it is taller than 3 feet. The 2024 Phoenix Building Construction Code exempts fences, other than swimming pool barriers, not over 3 feet high, and it also exempts replacement of an existing permitted fence of the same material, height and location at a single-family home. Fences between 3 and 7 feet need a permit, but the code says that permit is issued for city code and Zoning Ordinance requirements only, which in practice means the city checks height, location, visibility triangles and site drainage rather than engineering. The city's fence guideline (TRT 00181) adds the other half: structural calculations are not required for individual fences 7 feet or less, fences over 7 feet require structural design, and a combined fence-on-retaining-wall over 9 feet needs zoning approval before the permit. The word fence covers wood, metal, masonry, screen walls and view walls alike.

How Much Does a Fence Permit Cost in Phoenix?
The 2026 Development Fee Schedule prices fence permits on valuation, and Table A carries a special line: projects valued at $1 to $1,000 pay a $98 minimum for residential water heaters and fences. Valuation comes from the city's Miscellaneous Construction guide, which lists chain-link or wood fences at $24.00 per linear foot, masonry at $42.30, wrought iron at $30.85 and Dooley block at $27.87. Forty feet of wood fence is $960 of valuation, so the permit is $98. One hundred feet of wood fence is $2,400; Table A charges $195 on the first $1,000 plus $12 for each additional $1,000 or fraction, so $195 + 2 x $12 = $219. A 150-foot block wall is $6,345; that is $195 + 6 x $12 = $267. Permits valued at $1,000 or less include a maximum of two inspections. The schedule waives plan review on jobs under $5,000 that are handled at the counter in 15 minutes or less; above $5,000 a plan review fee equal to the permit fee applies only if a plan review is actually required, so ask before you budget an extra $267 for that block wall.
Height Limits Are a Zoning Question
The building permit is not the height limit. TRT 00181 says all fences must meet the Zoning Ordinance and traffic visibility requirements, which in most cases limit the height of fences to 3 feet in required front yards and in visibility triangles at driveways and street intersections. Section 703 of the Zoning Ordinance sets how fence and freestanding wall height is measured. Hillside and preservation lots are handled site by site. The Fence Permit Application also makes you sign a fence placement statement: you are responsible for verifying your property lines, at your own expense if a surveyor is needed. Anything in the public right-of-way is a separate question covered by the city's structures-in-the-right-of-way guidance.
Who Files and How
The Fence Permit Application asks for address, valuation, total length, height and type of fence, and whether the applicant is the owner or an ROC-licensed contractor; residential permits go through the SHAPE PHX portal. An owner who will occupy the home may do the work under ARS 32-1121.A.5. A permit for a temporary construction or security fence is valid for one year. Under the 2024 code every other permit expires 24 months after issuance, and building without one costs an investigation fee of at least $250 plus a doubled permit fee.
How to Get a Fence Permit in Phoenix
Measure height from final grade
3 ft or under, or an in-kind replacement of a permitted fence: no permit. Otherwise file.
Check zoning height and visibility triangles
Front yards and driveway or intersection triangles are generally capped at 3 ft; Section 703 governs how height is measured.
Fill out the Fence Permit Application
Address, valuation, length, height, material, owner or ROC contractor, and the signed fence placement statement.
Submit in SHAPE PHX with a plot plan
Show the fence location and height on a scaled plot plan; fences over 7 ft or on retaining walls add structural calculations.
Pay and build
$98 minimum or Table A on valuation; permits up to $1,000 include two inspections. Request inspections before 2 p.m. the prior business day.
